To all whom t may concern Beit known ythat 1,. GEORGE B. Konmar, a citizen of theUnited States, residing'in Philadelphia, Pennsylvania, have invented certain Improvements in Guides for Pivoted Doors,y of which 'the following is a yspecifica` tion.` i Q i This invention relates to certain impr`ove-1 ments in meansfor guiding the outer section of a *multiple-section' pivoted door, where one section folds against anothersectionf 1 -The invention is particularly adapted for use in railway passenger cars where it isdesired to so locate the kmechanism that when the door vis'open it will extend partly over the platform.- fv i f Ieretofore, it has been necessary to prof vide a cam-shaped or curvedr guide rail for the outer door section when the pivot for the door was inside the planeof the doors when the doors were closed, consequently, the roller would not workfreely'in the guide and in many instances itwould bind, preventing the full opening ofthe door/s. y i

The object of my invention is to so i1n` prove the construction that a straight rail can be used, the rollers traveling freely along the guide rail from the open to the closed position. f

In the accompanying drawings z-Figure 1, is a view, in elevation, of the upper portion of a car door and frame, showing the door in the closed position and illustrating my invention; Fig. 2, is a plan view ofthe door and frame, showing the doorin the closedposition; Fig. 3, is a view, similar to Fig. 2, with the door in the open position; Fig. 4, is a sectional view on the line a-a, Fig. 1; Fig. 5, is a perspectiveview. of the heading of the door, showing the straight guide rails; Fig. 6is a view of the upper portion of thel door, showing the rollers which are adapted to the guide rails; Fig. 7, isa detached perspective view of the bracket and the roller guide detached; Fig. 8, is a sectional view of the bracket and roller guide, showing the upper end of the door in dotted lines; and Figs. 9 and 10, are views of modifications of the invention.

Referring to the drawings, 1 is the frame of the door.

2 is the guide rail, which is securedto the head portion of the frame 1, as illustrated in Fig. 5, and 8 is the other rail separated GUIDE. non riverain nocns. {f

from the rail 2 a suiiicient distance to allow the guide rollers to travel inthe space. Both of `these rails are straight and vextend the' full width ofthe dooropening.

4 is the `inner. section Vof the door and 5 is vG0 the outer section, being pivoted to theinner resented nee. a', isis.

section by any suitable type of hinges G, so i that the sections of the door, when open, will assume the positionr/illustrated in F ig; 3.

.7 is theupper pivot bracket for the door, n

f having a pivot pin 8 which enters a socketv 9 in a. bracket 10, which is secured to the inner section 4 of the door.

lt will be noticed that both brackets are extended s0 that the pivot point is'somed-istance from the. door f' frame `and from the inner surface of the door, and thatthepivot bracket 10 of theA illustratedin Fig. 8, extending partlyiover thedoor frame and partly over the platform. Consequently,the door does'not project beyond the side frame of the car.

Secured to the outer door section 5, preferably some distance from the pivotk point, as indicated in Fig. 1, is a bracket 11; the door being recessed at the upper edge, as indicated in Figs. 1 and 4 to receive the bracket, and pivoted at 12 to the projecting portion of the bracket is a yguide 13 having two pins 14 on which are mounted the rollers 15. These rollers travel between' the two rails 2 and 3 and guide the outer section of the door as the door is opened and closed. The pivot 12 projects beyond the outer face of the door, as illustrated in Figs. 4 and 6, so that, when the door is moved, the rollers control the guide 13, keeping it from turning but allowing Vit to slide freely between the rails while the bracket and the door section 5 turn on `the pivot 12 so that, when the door is in the closed position, the section 5 will assume the position clearly shown in Fig. 3. Thus curved rails are dispensed with andl a constructionis provided which will ailow the door to open and close with the least amount of friction.

Any suitable mechanism may be used for opening and closing the doors, or the doors may be opened or closed by hand, if desired.

In Fig. 9,1 have shown the invention appliedto a single rail 2, in which instance the -l as "illustrated inFig. 6; g;
